De-Risking Financial Infrastructure Through Rigorous Architectural Research
Authoritative technical whitepapers, failure mode post-mortems, ISO 20022 schemas, and migration taxonomies developed from 18+ high-consequence core banking deployments. Written for Chief Architects, CIOs, and Supervisory Boards.
The Deterministic Core Strangler: Surviving Coexistence and Shadow Ledgers Without Dual-Run Data Drift
A comprehensive 48-page blueprint detailing how Tier-1 banks decouple 30+ year old legacy mainframes using event-driven Change Data Capture (Debezium/Kafka), transactional outbox patterns, sub-second continuous balance validation, and automated idempotent rollback circuits. Includes production-tested architectural schemas.
